Eph 6:18 With prayers and deep desires, making requests at all times in the Spirit, and keeping watch, with strong purpose, in prayer for all the saints,
Eph 6:19 And for me, that words may be given to me in the opening of my mouth, to make clear without fear the secret of the good news,

Love the Lord your God with all you are

Luke 10:27
And he, answering, said, Have love for the Lord your God with all your heart and with all your soul and with all your strength and with all your mind; and for your neighbour as for yourself.

Set your heart on God’s work as Solomon did.

And all the work of Solomon was complete, from the day when he put the base of the Lord’s house in position, till Solomon had come to the end of building the Lord’s house.
